INVENTOR Patented Apr. 25, 1950 OFFICE $2,505,169 :JEWEBRYCHAIN WITHYINTEGRAL'IPINS iIonas' Bik-off, Brooklyrn NiY. Application April '1, 194a, seriaiind massr 6 Claims. (01559- 80 This invention "relatesto flexible, flatjbroad jewelry chains, particularly fOl"bl8Jce1ts, and has for its maincobjectitoxprovide aichain of this character which will be composed of identical ,links 7 and inexpensive manufacturing and assembling will be made possible, and to eliminate need for two differently shaped links for bracelets of this type.

Another object of this invention is to provide a jewelry chain of the mentioned character, in which no separate pins are used, but the pivot pin between the links of the chain will be integral with, and part of, the links themselves, whereby extra labor, complications in manufacturing and use, will be avoided.

' Other objects of this invention will be apparent as the specification of the same proceeds, and among others, I may mention to eliminate the need of having two differently shaped links, as has been the case with bracelets of this type heretofore.

In the drawings forming a part of this specification and accompanying the same:

Fig. 1 is a plan vie-w of a portion of a chain constructed according to my invention;

Fig. 2 shows the blank of a link in said chain;

Fig. 3 is an end view and indicates the way said blank is bent when the chain is being manufactured, the view beingtaken as indicated by arrow 3 in Fi 4;

Fig. 4 is a sectional view, the section being taken on the line 4-4 of Fig. 3;

Fig. 5 is a side view of a portion of the assembled chain, the last four figures being on a larger scale than Fig, 1.

Referring now to the drawings more in detail by characters of reference, the numeral l indicates the blank of a link in my chain, in general, and the same will be made of a piece of flexible but shape retaining sheet material, like metal, and it will have a body portion l I, arms l2 at one side thereof, and arms I3 at the other side, the two arms being alternately spaced, having the respective spaces l4 and I between them.

A portion l6 of the material of the blank between the arms l2 will be left intact forming a bridging piece between the arms l2, which ultimately will be used as the pivot pins for the chain.

Informing "the chain, the hook formed by the doubling, in a spaced apart-manner,'of -the-arm I3,*willbemade to embrace the pin portion l6 'of the "adjacent link, indicated in Fig.' 5 and shown in; a'plan view'in Fig. 1.

' In this'manner the jewelry chain maybe formed with very closely fitting portions in its design and of a very simple construction.

I also prefer to have the pin forming portions [6 be of considerable width and provide partial transverse separation lines or incisions I9 at the ends of their sides 20, so that upon forming the links their separated portions may be bent more inwardly than the arms I2 as indicated in Figs. 4 and 5, said more inwardly bent portions 20 engaging arms l3 of the adjacent link and thereby causing the links to be drawn closer to another, (Fig. 5).

While I have shown a preferred embodiment of my invention, it is to be understood that changes and variations may be resorted to in the elements, construction and combination of my invention, and I reserve my rights to such changes, variations and uses, as are within the spirit of this specification, and the scope of the claims hereunto appended.

What I claim as new and want to protect by Letters Patent of the United States, is:

1. In a jewelry chain composed of a plurality of links of sheet material, each link having a body portion in the plane of the chain but transversely to the longitudinal axis of the chain, and alternately placed arms projecting from opposite sides of each link, the combination therewith, of individual comparatively short pins secured between each pair of arms on one side of each link, the end portions of the arms on each side being bent doubled but in a spaced apart manner on e the same side of the plane of the chain, and the arms l3 on the dotted line I8, which preferably hooks so formed by the bending of the pinless arm in one link being placed to pivotally embrace the pins between the respective arms in the adjacent link.

2. In a jewelry chain, composed of a plurality of links of sheet material, each link having a body portion in the plane of the chain but transversely to the longitudinal axis of the chain, and alternately placed arms projecting from opposite sides of each link, the combination therewith, of individual comparatively short pins secured between each pair of arms on one side of each link, the end portions of the arms on each side being bent doubled but in a spaced apart manner on the same side of the plane of the chain, and the hooks so formed by the bending of, the pinless arms in one link being placed to pivotally embrace the pins between the respective arms in the adjacent link, each link being formed of one integral piece of sheet material including said pins.

3. In a jewelry chain, composed of a plurality of links of sheet material, each link having a body portion in the plane of the chain but transversely to the longitudinal axis of the chain, and alternately placed arms projecting from opposite sides of each link, the combination therewith, of individual comparatively short pins secured between each pair of arms on one side of each link, the end portions of the arms on each side being bent doubled but in a spaced apart manner on the same side of the plane of the chain, and the,

hooks so formed by the bending of the pinless arms in one link being placed to pivotally embrace the pin between the respective arms in the adjacent link, the arms and the pins between them being bent doubled substantially on the center line of said pins.

4. In a jewelry chain, as set forth in claim 1, said pins being flat, substantially wide plate portions, the arms at their sides and the pins themselves being bent on about the center lines of the pins.

5. In a jewelry chain, as set forth in claim 1, said pins being flat, substantially wide plate portions, the arms at their sides and the pins themselves being bent on about the center lines of the pins, a portion of the plate pins being separated and bent inwardly on a sharper curve than the arms on their side whereby said inwardly bent portion will engage the bent pinless arms of the adjacent link in the chain and draw said two links closer to one another.

6. In a jewelry chain, as set forth in claim 1, said pins being fiat, substantially wide plate portions, the arms at their sides and the pins themselve being bent on about the center lines of the pins, said plate pins being an integral part of the sheet material from which the blank for the link is formed.
